Introduction to the IBOY Macrofauna database
Many of you may be familiar with
a database on soil macrofauna, which began to be developed by
the Macrofauna network almost 15 years ago, under the supervision
of Carlos Fragoso, at the Instituto de Ecologia, in Xalapa, Mexico.
Although the database was originally created for earthworm communities,
it took into account all the soil macrofauna, and results on macrofauna
communities were entered into the database from various sites
all over the world.
The first major analysis of the world's soil macrofauna communities,
based on this initial database, appeared in the chapter by Lavelle
et al. (1994) in the book Biological Management of Tropical Soil
Fertility. In this analysis, 73 macrofauna communities sampled
using the TSBF hand-sorting method, from 29 sites under various
land use systems around the globe, were combined and the general
trends assessed via multi-variate analyses.
Since then, we estimate that over 700 comunities throughout the
world have been sampled using the standard or slightly-modified
TSBF methodology (See table in the attached word document; Macrofauna
available data table.doc). Many of us would like to know whether
the trends originally detected in the 1994 book chapter will remain
once the larger data-set is re-analysed, and if we can learn anything
new from this larger sampling effort. I am sure that many of you
would agree that there are certainly many interesting results
that would arise by combining all these macrofauna communities
into the Macrofauna database for re-analysis and re-interpretation.
However, the strength of this analysis depends very much on the
quality and the completeness of the data entered into the database.
